Service verification method and apparatus

ABSTRACT

Embodiments of the present disclosure provide a service-verification method and apparatus, wherein the method comprises: respectively receiving service parameters sent by a same user account on different terminals, respectively calculating corresponding service data according to the service parameters sent by each terminal; storing a plurality of corresponding relationships, each corresponding relationship comprising: service parameters sent by one terminal and corresponding calculated service data; when a service-processing request sent by any one of the different terminals is received and the service-processing request carries a target service parameter and target service data used in a current service, obtaining service data corresponding to the target service parameter according to the corresponding relationships; and acquiring a verification result according to a comparison between the obtained service data and the target service data.

FIELD

The present application relates to the field of computer technologies, in particular to a service-verification method and apparatus.

BACKGROUND

Some services may involve the calculation of dynamic data. For example, a user can use his wireless terminal to shop online and select shopping parameters (e.g., the delivery address) on the shopping page. The backend server of the shopping application can calculate corresponding service data (e.g., shipping cost corresponding to the delivery address) according to the parameter selected by the user, and display the service data on the terminal page for user confirmation. After user confirmation, the data can be used to execute service logic processing. In this case, the above service data is calculated based on the parameters selected by the user on the page. When the parameters selected by the user change, the corresponding service data also changes. This type of service data may be referred to as dynamic data.

In order to ensure service security, the dynamic data usually needs to be verified. For example, the backend server can store the service data in the cache after sending the calculated service data to the terminal page for display to the user. After the user confirms and submits the service data, it is checked whether the service data transmitted from the user terminal is the same as the above cached service data. If the two pieces of data are the same, the verification succeeds and the subsequent service processing is performed using the service data. If the two pieces of data are different, then the verification fails and the service procedure terminates.

DETAILED DESCRIPTION

In order for those skilled in the art to better understand the technical solutions in the one or more embodiments of the present disclosure, the technical solutions in the one or more embodiments of the present application are clearly and completely described below with reference to the drawings. It is obvious that the described embodiments are merely a part of the embodiments and not all of the embodiments. Based on the one or more embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

In an application scenario involving computation of dynamic data, it is possible that data submitted by a user can be tampered with. For example, when the same user account is used to operate on multiple terminals to obtain dynamic data, a service exception may occur.

For example, a user A selects, on his own wireless terminal a, a service parameter P1 on a page of a shopping application, and a backend server accordingly calculates corresponding service data D1 and stores it in the session. D1 can be displayed and stored on wireless terminal a for confirmation by user A. A user B uses, on another wireless terminal b, the same account as that of the user A to open the same page, but selects another service parameter P2. Accordingly, the backend server calculates another piece of service data D2, which is also stored in the session and overwrites D1. User A finally submits a service-processing request on the wireless terminal a, the service-processing request carrying service parameter P1 selected on wireless terminal a and the confirmed D1.

The above situation is a case of data tampering. User A originally selects the service parameter P1, but the user B tampers with the parameter, changing it into the service parameter P2 on another wireless terminal. Such tampering may be malicious or unintentional. Using a case where the tampering is actually caused by the user unintentionally as an example, user B is a relative or friend of user A and uses the account of user A to change the service parameter on another wireless terminal, but user A is unaware of this change. When user A submits a service-processing request on his own wireless terminal a, verification logic of the backend server compares D1 transmitted by the terminal with the service data stored in the session, and only considers the verification being successful when the two pieces of data are the same. As mentioned above, data stored in the session is replaced as D2, and D1 and D2 are different, the server then determines that the verification fails, notifies user A of a system exception, and interrupts the service processing. This can lead to the service of user A not able to be carried out normally.

That is, when the same account is operated on different terminals and calculation of dynamic data is performed on each terminal, service data from different terminals may overwrite one another in the session, resulting in mutual interference in the service verification on the different terminals and affecting service flow. In view of this, one or more embodiments of the present disclosure provide a service-verification method as shown in FIG. 1 to solve the above problem. The method shown in FIG. 1 may be executed by a backend server.

In operation 100, service parameters sent by the same user account on different terminals are respectively received, and the service parameters sent from the different terminals are different.

For example, the same user account sending service parameters on different terminals may be the same user using his same account to operate on different terminals, or different users using the same account to operate on different terminals. The service parameters sent from different terminals may be different. For example, the parameter sent by one terminal is P1, and the parameter sent by another terminal is P2.

In one example, the user account may be an account of an application, and different users can register respective accounts thereof on the application. For example, a user can register an account of a shopping application, and shop on the shopping application using the account. Service parameters sent by different terminals can all be sent to a backend server corresponding to the above-mentioned application. For example, the user logs into his account of the shopping application on a particular terminal, selects a service parameter, and sends the service parameter to the backend server of the shopping application.

In operation 102, corresponding service data is respectively calculated according to the service parameter sent by each terminal.

In this operation, the backend server can respectively calculate the corresponding service data according to the service parameter of each terminal. One terminal may send one or more service parameters, and the backend server may comprehensively calculate the corresponding service data according to the one or more service parameters. The manner of calculation can be determined according to service characteristics.

For example, a service parameter sent by one terminal can be one parameter p1, and then the server can calculate corresponding D11 according to p1; service parameters sent by another terminal can be two parameters p2 and p3, and the server can then calculate corresponding D12 according to p2 and p3.

In operation 104, a plurality of corresponding relationships are stored, and each corresponding relationship includes the service parameter sent by one terminal and the service data obtaining via a corresponding calculation.

The corresponding relationship in this operation can be used to indicate a corresponding relationship between the service parameter sent by one terminal and the service data calculated according to the service parameter. The service parameter and service data in the corresponding relationship are obtained before the backend server sends the service data to a page to display to the user for confirmation. For example, if the user selects service parameters p2 and p3 on the terminal page, the backend server can calculate and acquire D12 according to these two parameters, and then send D12 to the terminal page to display for user confirmation. The server then stores a corresponding relationship between the above “p2 and p3” and “D12.” Certainly, the corresponding relationship described herein may be an identifier calculated according to “p2 and p3.”

In operation 106, when a service-processing request sent by any one of the different terminals is received and the service-processing request carries a target service parameter and target service data used in a current service, service data corresponding to the target service parameter is obtained according to the corresponding relationship.

Since the backend server stores the corresponding relationship between the service parameter sent by each terminal and the service data, for a service-processing request sent by any terminal, service data corresponding to the service parameter in the request can be found according to the corresponding relationship. The service-processing request in this operation may be submitted after the user confirms the service data displayed on the terminal page. The service parameter and service data carried in the request may be respectively referred to as target service parameter and target service data.

In operation 108, a verification result is acquired according to a comparison between the obtained service data and the target service data.

In this example, a comparison can be made to determine whether the service data obtained in operation 106 and the target service data are the same. If they are same, it is considered that the verification is successful, a service corresponding to the service-processing request is executed using the target service data, and the target service data is saved to a database. According to this method, even if there are multiple terminals operated by the same account, regardless of which terminal is submitting the service-processing request, it is only needed to check whether a service parameter sent by the terminal that submits the request matches the service data (a matching means that the service data can be calculated according to the service parameter). In addition, the server stores the corresponding relationship between the service parameter and the service data, and the service data in this corresponding relationship is calculated by the server itself and can be guaranteed to be truthful and accurate. An accurate determination as to whether the service parameter in the service-processing request matches the service data can be made according to the corresponding relationship.

Otherwise, if the service data is different from the target service data, then it can be determined that the verification fails and the service-processing request is rejected. In this case, the verification failure may result from, for example, the user accidentally or intentionally modifying the service parameter, resulting in the service data acquired by the server according to the modified service parameter being different from the target service data. At this time, the server does not allow the user to perform subsequent operations, and an exception notification is provided.

In the above service verification method, the corresponding relationships between service parameters and service data of different terminals are stored, such that, even if a same account is sending a service parameter on different terminals, data in the session will not be overwritten. Therefore, service verification of each terminal can be respectively and independently performed, thereby preventing interference between different terminal operations.

A case where a user creates a shopping order on a wireless terminal is taken as an example below to describe the service-verification method provided in one or more embodiments of the present disclosure. Referencing the interaction diagram shown in FIG. 2, the method may include:

In operation 200, user A opens a shopping page on the wireless terminal a.

For example, user A can request to open the shopping page for shopping on his wireless terminal a, in a manner of entering the address of the shopping page in a browser or clicking a link to the address of the shopping page. Wireless terminal a can request page data from the backend server corresponding to the shopping page, perform page rendering according to the data returned by the server, and display the shopping page to user A.

Wireless terminal a in this example can be referred to as a first terminal. The term “first” is merely used for distinguishing the names of different terminals that appear subsequently, and does not have a limiting effect. Subsequently appeared terms “first,” “second,” etc. have the same principle. In addition, user A can also log in his account L on wireless terminal a.

In operation 202, user A selects service parameters on the shopping page via the wireless terminal a.

For example, the user selects the service parameters, including: param_1, param_2, . . . , and param_N. These parameters can be referred to as first service parameters.

In operation 204, wireless terminal a requests service data corresponding to the service parameters from the backend server.

For example, wireless terminal a can request to obtain the corresponding service data via a backend interface according to the first service parameters selected by the user. Specifically, wireless terminal a sends a service-data request to the backend server, which may carry the first service parameters and a user account L.

In operation 206, the server calculates service data according to the service parameters.

In this operation, the backend server can calculate, according to the first service parameters “param_1, param_2, . . . , param_N” to obtain the corresponding service data result_1, and service data result_1 can be referred to as a first service data.

In operation 208, the server stores a corresponding relationship between the service data and the service parameters in a distributed cache.

For example, storage can be performed using a Key-Value manner and calculation is performed in the following manner:

Calculation of a Key: all the parameters in the first service parameters are added and hashed to obtain a hash value, wherein the hash value can be used as a Key. For example, assuming that the first service parameters can include “param_1, param_2, . . . , param_N,” hash (param_1+param_2 . . . +param_N) can be used as a key. When each parameter (e.g., param_1) is a character string, the aforementioned Key can be obtained by adding these parameter character strings into a large character string and then performing hashing for the large character string.

Calculation of Value: the Value represents the service data. The manner in which the service data is calculated according to the service parameters can be determined according to specific service needs and characteristics. In this example, result_1 in operation 206 can be used as a Value.

The server can store a corresponding relationship between the hash value and the service data. For example, the corresponding relationship can be stored in the distributed cache in the form of Key-Value. In addition, a corresponding relationship between the first service parameters and the first service data can be stored in a storage space corresponding to the user account L.

In operation 210, the server returns the calculated service data to wireless terminal a.

In this operation, the server can send result_1 to the wireless terminal a for confirmation by user A.

Assuming that a relative or friend of user A uses account L of user A to create a shopping order on an another wireless terminal b, then the following operations can be executed:

In operation 212, user B opens the shopping page on wireless terminal b.

Wireless terminal b can be referred to as a second terminal.

In operation 214, user B selects service parameters in the shopping page via wireless terminal b.

For example, the user selects the service parameters including “param_11, param_21, . . . , and param_NN.” These parameters can be referred to as second service parameters.

In operation 216, wireless terminal b requests service data corresponding to the service parameter from the backend server.

For example, wireless terminal b can request to obtain the corresponding service data via a backend interface according to the second service parameters selected by the user. Specifically, wireless terminal b sends a service data request to the backend server, which may carry the second service parameters and user account L. The same user account L is used on wireless terminal b and wireless terminal a.

In operation 218, the server calculates the service data according to service parameters.

In this operation, the backend server can calculate and acquire the corresponding service data result_2 according to the second service parameters “param_11, param_21, . . . , and param_NN,” and service data result_2 can be referred to as second service data.

In operation 220, the server stores a corresponding relationship between the second service data and the second service parameters in the distributed cache.

In this operation, the manner for the calculation of Key-Value is the same as that in operation 208 and is not described herein in detail.

The server also stores the corresponding relationship between the second service data and the second service parameters in the storage space corresponding to user account L. As described above, when storing a corresponding relationships, regardless of whether the storage space stores other corresponding relationships, the server does not perform data overwriting, but stores a plurality of corresponding relationships in the space. For example, the storage space corresponding to user account L stores at least two corresponding relationships as shown in Table 1 below. Table 1 shows that user account L is logged in on the two terminals, both having configured parameters:

TABLE 1 Corresponding relationships Key Value hash (param_1 + param_2 . . . + param_N) result_1 hash(param_11 + param_21 . . . + param_NN) result_2

In operation 222, the server returns the calculated service data to wireless terminal b. For example, the server can send result_2 to the wireless terminal b.

Although both user A and user B use account L to configure parameters on their respective terminals, in this example, in the end it is user A who submits an order on wireless terminal a for confirmation.

In operation 224, user A submits the order on wireless terminal a.

For example, on wireless terminal a, user A confirms page information that he filled out and confirms result_1. Considering that an order can be created, user A can click order-creation on the page on wireless terminal a to request the server to create the order, which can be referred to as sending a service-processing request to the server. It should be noted that, at this time when the service-processing request is submitted to the server, the parameters carried are still result_1, as well as the first service parameters “param_1, param_2, . . . , and param_N” configured by user A. The first service parameters can be referred to as the target service parameters, and result_1 can be referred to as the target service data.

In operation 226, the server obtains the service data corresponding to the target service parameters according to the corresponding relationship.

For example, the server can perform a hashing operation on “param_1, param_2, . . . , and param_N,” thus obtaining Key=hash (param_1+param_2 . . . +param_N). In addition, the service data result_1 corresponding to the service-processing request can be acquired from the storage space of user account L in the distributed cache, according to the corresponding relationship in Table 1.

In operation 228, the server acquires a verification result according to the comparison outcome between the service data and the target service data.

For example, if the service data obtained in operation 226 is the same as the target service data, then the verification is determined as successful, and the service corresponding to the service-processing request is executed using the target service data. For example, an order can be created using result_1, and target service data result_1 can be saved to the database.

If the obtained service data is different from the target service data, then the verification is determined as failed, and the service-processing request is rejected, that is, the order is not created for the user. In this case, the verification failure may result from the user intentionally tampering with the data. For example, instead of choosing to configure the service parameters on the shopping page, the user modifies the parameters while the wireless terminal is transmitting the parameters to the server. In this case, the user is not allowed to perform subsequent operations, and an exception can be displayed.

In addition, another possibility is that: when the service parameters are tampered with during the transmission from the wireless terminal to the server, it is possible that the tampered service parameters do not exist in the corresponding relationships stored in the distributed cache, then the server can perform a recalculation according to the service parameters (that is, the service parameters after tampering, which can also be referred to as the target service parameters, and the service parameters carried in the service-processing request can be referred to as the target service parameters) transmitted by the wireless terminal, and the acquired service data can be referred to as new service data. The new service data can be compared with the target service data (the service data carried in the service-processing request can be referred to as the target service data) to determine whether the two pieces of data are the same. If the two pieces of data are the same, then the verification succeeds; otherwise, it can be determined that the verification fails.

By storing the service parameters sent by each terminal of the same account and the corresponding calculated service data in the cache, the service-verification method of this example can ensure that verification logic of individual terminals does not interfere with each other. Regardless of the wireless terminal on which the user submits the data, a system can extract the corresponding service data from the cache according to the parameters transmitted by the terminal and compare it with the submitted service data to determine whether the verification succeeds. According to this method, when performing calculation involving dynamic data, if different users use the same account to perform an operation of obtaining dynamic data on different wireless terminals, regardless of which user is performs the operation and on which wireless terminal the operation is performed, it can be ensured that the data submitted by the user is not tampered with and a service is carried out normally without interruption, thereby ensuring a better service flow.

In order to implement the above service-verification method, one or more embodiments of the present disclosure further provide a service-verification apparatus. As shown in FIG. 3, the apparatus may include: a parameter-receiving module 31, a data-calculation module 32, a relationship-storage module 33, a data-obtaining module 34, and a comparison-verification module 35.

Parameter-receiving module 31 is configured to respectively receive service parameters sent by the same user account on different terminals. Service parameters sent by the different terminals are different.

Data-calculation module 32 is configured to respectively calculate corresponding service data according to the service parameters sent by each terminal.

Comparison-verification module 35 is configured to acquire a verification result according to a comparison outcome between the obtained service data and the target service data.

In one example, relationship-storage module 33 is specifically configured to: when one terminal sends multiple service parameters, perform hashing for the sum of the multiple service parameters to acquire a hash value; and store a corresponding relationship between the hash value and the service data.

In one example, comparison-verification module 35 is specifically configured to:

if the obtained service data is the same as the target service data, then determine that verification succeeds, execute the service corresponding to the service-processing request using the target service data, and store the target service data in a database; and

if the obtained service data is different from the target service data, then determine that the verification fails, and reject the service-processing request.
